function SetUsageType (
lInputID : int,
pIDTSVirtualInputObject : IDTSVirtualInput100,
lLineageID : int,
eUsageType : DTSUsageType
) : IDTSInputColumn100
Parameters
- lInputID
The ID of the IDTSInput100.
- pIDTSVirtualInputObject
The IDTSVirtualInput100 object that contains the virtual input column and that is used to map the IDTSInputColumn100 object.
- lLineageID
The LineageID property of the IDTSVirtualInputColumn100 object.
- eUsageType
A value from the DTSUsageType enumeration that is assigned to the IDTSInputColumn100.
Return Value
The IDTSInputColumn100 object whose UsageType is set.
Remarks
SetUsageType is called when a column from the IDTSVirtualInputColumnCollection100 is selected for a component. If the usageType is UT_READONLY or UT_READWRITE, a new input column is created for the component that reflects the IDTSVirtualInputColumn100 specified by the lLineageID parameter. If usageType is UT_IGNORED and the column exists in the collection, the column is removed and null is returned.
